* Don't construct or delete a module on the Linker.Rafael Espindola2013-05-041-7/+0
| | | | | | | The linker is now responsible only for actually linking the modules, it is up to the clients to create and destroy them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181098 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for reading ARM ELF build attributes.Amara Emerson2013-05-032-0/+525
| | | | | | | | | | | | Build attribute sections can now be read if they exist via ELFObjectFile, and the llvm-readobj tool has been extended with an option to dump this information if requested. Regression tests are also included which exercise these features. Also update the docs with a fixed ARM ABI link and a new link to the Addenda which provides the build attributes specification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181009 91177308-0d34-0410-b5e6-96231b3b80d8

* This exposes more MCJIT options via the C API:Filip Pizlo2013-05-012-11/+57
| | | | | | | | | | | | | | | | | | | | | | | CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like. Previously it was only possible to create an MCJIT that used CodeModel::JITDefault. EnableFastISel: It's now possible to turn on the fast instruction selector. The CodeModel option required some trickery. The problem is that previously, we were ensuring future binary compatibility in the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the bindings then bzero the remaining bits. This works great but assumes that the bitwise zero equivalent of any field is a sensible default value. But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model. In both of those, the default for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero. Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp illustrates the change, as does the comment in ExecutionEngine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180893 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo2013-05-0113-126/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8

* Change getSlotIndex to return unsigned.Rafael Espindola2013-04-301-1/+1
| | | | | | | | | | | The actual storage was already using unsigned, but the interface was using uint64_t. This is wasteful on 32 bits and looks to be the root causes of a miscompilation on Windows where a value was being sign extended to 64bits to compare with the result of getSlotIndex.

| | | | | | | | | | | | | For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

* Add target flags to MachineMemOperands.Andrew Trick2013-04-271-1/+7
| | | | | | | | | | | | | | | | | | This seems to me an obvious place to allow target passes to annotate memory operations. There are plenty of bits, and I'm not aware of another good way for early target passes to propagate hints along to later passes. Target independent transforms can simply preserve them, the way they preserve the other flags. Like MachineMemOperands in general, if the target flags are lost we must still generate correct code. This has lots of uses, but I want this flexibility now to make it easier to work with the new MachineTraceMetrics analysis. MachineTraceMetrics can gather a lot of information about instructions based on the surrounding code. This information can be used to influence postRA machine passes that don't work on SSA form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180666 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | to determine whether or not we're on a darwin platform for debug code emitting. Solves the problem of a module with no triple on the command line and no triple in the module using non-gdb ok features on darwin.

Unfortunately no testcase because I have no ideas how to test something without a triple and without a triple in the module yet check precisely on two platforms.

* Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-263-289/+22
| | | | | | | | | | | | | | | | | | | | | For Mach-O there were 2 implementations for parsing object files. A standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which implements the generic interface in llvm/Object/ObjectFile.h. This patch adds the missing features to MachO.h, moves macho-dump to use MachO.h and removes ObjectFile.h. In addition to making sure that check-all is clean, I checked that the new version produces exactly the same output in all Mach-O files in a llvm+clang build directory (including executables and shared libraries). To test the performance, I ran macho-dump over all the files in a llvm+clang build directory again, but this time redirecting the output to /dev/null. Both the old and new versions take about 4.6 seconds (2.5 user) to finish. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180624 91177308-0d34-0410-b5e6-96231b3b80d8
